An update on the self-care of heart failure index

A Pilot Study to Evaluate a Computer-Based Intervention to Improve Self-care in Patients With Heart Failure

BACKGROUND

Cognitive dysfunction contributes to poor learning and impaired self-care (SC) for patients with heart failure.

OBJECTIVES

The aims of this study were to (1) evaluate the feasibility and acceptability of a nurse-led, virtual home-based cognitive training and SC education intervention to support SC and (2) evaluate the relationship between improvements in SC and cognitive change and examine 30-day readmission rates.

METHODS

In this 2-phase pilot study, we used a prospective, exploratory design. In phase 1, recruitment criteria and retention issues threatened feasibility and acceptance. Significant modifications were made and evaluated in phase 2.

RESULTS

In phase 2, 12 participants were recruited (7 women and 5 men). Feasibility was supported. All participants and the study nurse positively evaluated acceptability of the intervention. Median SC scores improved over time. Thirty-day hospital readmission rates were 25%.

CONCLUSION

Phase 1 indicates the intervention as originally designed was not feasible or acceptable. Phase 2 supports the feasibility and acceptability of the modified intervention. Further testing is warranted.

Cross-cultural applicability of the Self-Care Self-Efficacy Scale in a multi-national study

AIM

The Self-Care Self-Efficacy Scale (SCSES) was newly developed as a self-report measure for self-care self-efficacy for chronic illness. This study investigated its measurement equivalence (ME) in different cultural groups, including United States, China (Hong Kong), Italy, and Brazil.

DESIGN

A multi-national study for cross-cultural validation of the Scale.

METHODS

From January 2015 - December 2018, investigators recruited 957 patients (United State: 200; Hong Kong: 300; Italy: 285; and Brazil: 142) with chronic illness from inpatient and outpatient settings. The SCSES was administered and clinical and demographic data were collected from participants. Based on the Meredith framework, multi-group confirmatory factor analysis evaluated the configural, metric, scalar, and strict invariance of the scale across the four populations through a series of nested models, with evaluation of reliability and coherence of the factor solution.

RESULTS

The mean ages of the groups ranged from 65-77 years, 56.4% was male. The Cronbach's alpha coefficients of the single-factor SCSES were 0.93, 0.89, 0.92, and 0.90 for the United States, China (Hong Kong), Italy, and Brazil, respectively. Three of the four levels of ME were partially or totally supported. The highest level achieved was partial scalar invariance level (χ² [52] = 313.4, p < 0.001; RMSEA = 0.067; 95% CI = 0.056-0.077; CFI = 0.966; TLI = 0.960, SRMR = 0.080).

CONCLUSION

Patients from the four countries shared the same philosophical orientation towards scale items, although some of the items contributed differently to represent the concept and participants shared the same schemata for score interpretation.

IMPACT

Self-efficacy is important in producing effective and sustainable self-care behavioural changes. Cultural ideation shapes the ways individuals interpret and report their self-care self-efficacy. The study findings support cross-cultural and cross-national utility of the SCSES for research on self-care across United States, China (Hong Kong), Italy, and Brazil.

Effects of an Empowerment Program on Self-Care Behaviors and Readmission of Patients with Heart Failure: a Randomized Clinical Trial

BACKGROUND

The prevalence of heart failure, as a serious health problem, is increasing around the world due to underlying factors, such as hypertension and diabetes. Although the patient's cooperation in the treatment process plays a crucial role in treatment, only a few combinations of different approaches have been investigated so far. This study aimed to determine the effects of an empowerment program on the patients' self-care behaviors and hospital readmission.

MATERIALS AND METHODS

In this randomized clinical trial, 120 patients with heart failure were divided into experimental and control groups. In the experimental group, the empowerment program, including face-to-face training, educational booklets, and follow-up via Telegram messaging application, was implemented, while the control group only received standard care. Data were collected before the intervention and six months after the intervention, using a researcher-made questionnaire. The Self-Care of Heart Failure Index (SCHFI) was completed for both groups.

RESULTS

The results indicated that all three self-care scales, namely, self-care maintenance, self-care management, and self-care confidence, significantly improved in the experimental group compared to the baseline (P=0.000), while the scores of these scales decreased in the control group (P=0.000). The frequency of hospital admission and the length of hospital stay also reduced in the experimental group (P=0.000 and P<0.001, respectively). There was no significant difference in terms of the demographic characteristics between the two groups.

CONCLUSION

The empowerment program significantly improved the patients' self-care behaviors and reduced the frequency and duration of hospitalization. Therefore, implementation of such programs is strongly suggested, especially in heart failure clinics.

Integrating remote monitoring into heart failure patients' care regimen: A pilot study

Background

Around 50% of hospital readmissions due to heart failure are preventable, with lack of adherence to prescribed self-care as a driving factor. Remote tracking and reminders issued by mobile health devices could help to promote self-care, which could potentially reduce these readmissions.

Objective

We sought to investigate two factors: (1) feasibility of enrolling heart failure patients in a remote monitoring regimen that uses wireless sensors and patient-reported outcome measures; and (2) their adherence to using the study devices and completing patient-reported outcome measures.

Methods

Twenty heart failure patients participated in piloting a remote monitoring regimen. Data collection included: (1) physical activity using wrist-worn activity trackers; (2) body weight using bathroom scales; (3) medication adherence using smart pill bottles; and (4) patient -reported outcomes using patient-reported outcome measures.

Results

We evaluated 150 hospitalized heart failure patients and enrolled 20 individuals. Two factors contributed to 50% (65/130) being excluded from the study: smartphone ownership and patient discharge. Over the course of the study, 60.0% of the subjects wore the activity tracker for at least 70% of the hours, and 45.0% used the scale for more than 70% of the days. The pill bottle was used less than 10% of the days by 55.0% of the subjects.

Conclusions

Our method of recruiting heart failure patients prior to hospital discharge may not be feasible as the enrollment rate was low. Once enrolled, the majority of subjects maintained a high adherence to wearing the activity tracker but low adherence to using the pill bottle and completing the follow-up surveys. Scale usage was fair, but it received positive reviews from most subjects. Given the observed usage and feedback, we suggest mobile health-driven interventions consider including an activity tracker and bathroom scale. We also recommend administering a shorter survey more regularly and through an easier interface.

The Self-Care of Heart Failure Index version 7.2: Further psychometric testing

Clinicians and researchers need valid and reliable instruments to evaluate heart failure (HF) self-care. The Self-Care of Heart Failure Index (SCHFI) is a theoretically driven instrument developed for this purpose. The SCHFI measures self-care with three scales: self-care maintenance, measuring behaviors to maintain HF stability; symptom perception, measuring monitoring behaviors; and self-care management, assessing the response to symptoms. After the theory underpinning the SCHFI was updated, the instrument was updated to version 7.2 but it was only tested in the United States. In this study we tested the psychometric characteristics (structural and construct validity, internal consistency, and test-retest reliability) of the SCHFI v.7.2 in an Italian population of HF patients. We used a cross-sectional design to study 280 HF patients with additional data collected after 2 weeks for test-retest reliability. Adults with HF (mean age 75.6 (±10.8); 70.8% in New York Heart Association [NYHA] classes II and III) were enrolled from six centers across Italy. Confirmatory factor analysis showed supportive structural validity in the three SCHFI v.7.2 scales (CFI from 0.94 to 0.95; RMSEA from 0.05 to 0.07). Internal consistency reliability estimated with Cronbach's α and composite reliability ranged between .73 and .88; test-retest reliability ranged between 0.73 and 0.92. Construct validity was supported with significant correlations between the SCHFI v.7.2 scale scores and quality of life, brain natriuretic peptide levels and NYHA class. This study further supports the psychometric characteristics of the SCHFI v.7.2, illustrating that it can be used in clinical practice and research also in an Italian population.

The Contribution of Living Arrangements, Social Support, and Self-efficacy to Self-management Behaviors Among Individuals With Heart Failure: A Path Analysis

BACKGROUND

Living arrangements, social support, and self-efficacy have significant implications for self-management science. Despite the theoretical linkages among the 3 concepts, there is limited empirical evidence about their interplay and the subsequent influence on heart failure (HF) self-management.

OBJECTIVE

The aim of this study was to validate components of the Individual and Family Self-management Theory among individuals with HF.

METHODS

This is a secondary analysis of cross-sectional data generated from a sample of 370 individuals with HF. A path analysis was conducted to examine the indirect and direct associations among social environment (living arrangements), social facilitation (social support) and belief (self-efficacy) processes, and self-management behaviors (HF self-care maintenance) while accounting for individual and condition-specific factors (age, sex, race, and HF disease severity).

RESULTS

Three contextual factors (living arrangements, age, and HF disease severity) had direct associations with perceived social support and self-efficacy, which in turn were positively associated with HF self-management behaviors. Living alone (β = -.164, P = .001) was associated with lower perceived social support, whereas being an older person (β = .145, P = .004) was associated with better support. Moderate to severe HF status (β = -.145, P = .004) or higher levels of perceived social support (β = .153, P = .003) were associated with self-efficacy.

CONCLUSIONS

Our results support the Individual and Family Self-management Theory, highlighting the importance of social support and self-efficacy to foster self-management behaviors for individuals with HF. Future research is needed to further explore relationships among living arrangements, perceived and received social support, self-efficacy, and HF self-management.

Exercise and Cognitive Training Intervention Improves Self-Care, Quality of Life and Functional Capacity in Persons With Heart Failure

This study evaluated a 12-week, home-based combined aerobic exercise (walking) and computerized cognitive training (EX/CCT) program on heart failure (HF) self-care behaviors (Self-care of HF Index [SCHFI]), disease specific quality of life (Kansas City Cardiomyopathy Questionnaire [KCCQ]), and functional capacity (6-minute walk distance) compared to exercise only (EX) or a usual care attention control (AC) stretching and flexibility program. Participants (N = 69) were older, predominately female (54%) and African American (55%). There was significant improvement in self-care management, F(2, 13) = 5.7, p < .016; KCCQ physical limitation subscale, F(2, 52) = 3.4, p < .039; and functional capacity (336 ± 18 vs 388 ± 20 m, p < .05) among the EX/CCT participants. The underlying mechanisms that EX and CCT targets and the optimal dose that leads to improved outcomes are needed to design effective interventions for this rapidly growing population.

The multiple mediating effects of health literacy and self-care confidence between depression and self-care behaviors in patients with heart failure

BACKGROUND

Previous researchers have found that depression can influence self-care behaviors of patients with heart failure (HF). However, the specific path of depression on self-care behaviors remains unclear.

OBJECTIVES

To determine the multiple mediating effects of health literacy and self-care confidence between depression and self-care behaviors in patients with HF.

METHODS

A cross sectional study on HF patients (n = 310) was conducted at a tertiary hospital in China. The Chinese versions of the Hospital Anxiety and Depression Scale (HADS-D), Health Literacy Scale for Patients with Chronic Disease and Self-care of Heart Failure Index (C-SCHFI) were used to assess depression, health literacy, self-care confidence and self-care behaviors of the HF patients respectively.

RESULTS

Depression had significant negative correlations with health literacy (r = -0.40, P < 0.01), self-care confidence (r = -0.41, P < 0.01), self-care maintenance (r = -0.18, P < 0.01) and management (r = -0.19, P < 0.01). After controlling for covariates, mediation modeling analysis showed that health literacy and self-care confidence were mediating variables between depression and self-care management and all the three paths were significant. A higher level of depression debilitated health literacy (β = -0.23, P < 0.001), and a higher degree of health literacy was associated with better self-care confidence (β = 0.31, P < 0.001) which contributed to better self-care management (β = 0.43, P < 0.001). Total mediation effect was -0.1940 with 95% CI from -0.2702 to -0.1266. However, self-care confidence did not mediate between depression and self-care maintenance.

CONCLUSION

Health literacy and self-care confidence exert a multiple mediating effect on the relationship between depression and self-care management. The relationship between variables should be considered when developing the tailored interventions for patients with HF to enhance their self-care behaviors.

Heart Failure Self-care Associated With Brain Injury in Executive Control Regions

BACKGROUND

Inadequate self-care is linked to poor health outcomes in heart failure (HF). Self-care depends on decision-making abilities, but links between self-care and brain injury to executive decision-making regulatory areas (prefrontal cortices) are unclear.

OBJECTIVE

We investigated the relationships between HF self-care and status of prefrontal cortices.

METHODS

Magnetic resonance imaging-based diffusion tensor imaging was performed in 21 patients with HF (age, 53.8 ± 7.9 years; 15 men; left ventricular ejection fraction, 25.1% ± 6.1%), and self-care and executive function were measured with the Self-care of Heart Failure Index (SCHFI) and Trail Making Test B. Using diffusion tensor imaging data, mean diffusivity (MD) maps were calculated and region-of-interest analyses were performed on the left and right prefrontal brain areas. Statistical analyses consisted of partial correlations (covariates, age, and gender).

RESULTS

The mean ± SD SCHFI scores were 70.78 ± 11.37 for maintenance, 70 ± 17.32 for management, and 74.91 ± 15.76 for confidence. The mean ± SD Trail Making Test B score was 90.2 ± 73.3 seconds. The mean ± SD MD values (higher values indicate tissue injury) of the left and right prefrontal cortices were 1.46 ± 0.16 (×10 mm/s) and 1.44 ± 0.14 (×10 mm/s), respectively. Significant negative correlations emerged between prefrontal MD values and SCHFI maintenance (left/right, r = -0.64/-0.70; P < .003) and SCHFI management (r = -0.93/-0.86; P < .003). Significant positive correlations were observed between prefrontal MD values and Trail Making Test B (r = 0.71/0.74; P < .001). A nonsignificant correlation emerged between prefrontal MD values and SCHFI confidence scores.

CONCLUSIONS

Brain tissue integrity in executive function regulatory regions is associated with HF self-care for maintenance and management. The findings indicate that protection and brain injury repair in executive control areas may improve HF self-care.

Distinct Factors Associated With Better Self-care in Heart Failure Patients With and Without Mild Cognitive Impairment

BACKGROUND

A decline in cognition may limit patients' ability to effectively engage in self-care in those with heart failure (HF). However, several studies have shown no difference in self-care between HF patients with and without cognitive impairment. This may indicate that there are more salient factors associated with self-care in HF patients with cognitive impairment compared with those without cognitive impairment.

OBJECTIVE

The aim of this study was to explore which factors are related to self-care based on the presence and absence of mild cognitive impairment (MCI) among patients with HF.

METHODS

Patients with HF were recruited from outpatient settings. The Montreal Cognitive Assessment was used to screen for MCI. Self-care was measured with the Self-care of HF Index v.6.2. Two separate stepwise linear regressions were performed to identify which factors (HF knowledge, perceived control, functional status, multimorbidity, executive function, and social support) predicted self-care in HF patients with and without MCI.

RESULTS

Of the 132 patients in this study, 36 (27.3%) had MCI. Self-care maintenance and management were associated with social support (β = 0.489) and executive function (β = 0.484), respectively, in patients with MCI. Perceived control was associated with both self-care maintenance and management in patients without MCI (βs = 0.404 and 0.262, respectively).

CONCLUSION

We found that social support and executive function were associated with self-care in HF patients with MCI, whereas perceived control was associated with self-care in HF patients with intact cognition. Clinicians should develop tailored interventions to enhance self-care by considering the distinct factors associated with self-care based on the presence or absence of MCI.

The effects of a self-regulation programme on self-care behaviour in patients with heart failure: A randomized controlled trial

BACKGROUND

Self-care behaviour is important for patients with heart failure to prevent disease progression. More than half of patients have poor self-care behaviour. Self-regulation theory emphasizes that patients need to initiate monitoring of their symptoms, identify their own problems, and perform appropriate self-care behaviour. However, studies focused on interventions based on self-regulation theory for patients with heart failure are limited.

OBJECTIVES

To investigate the effects of a self-regulation programme on self-care behaviour in patients with heart failure.

DESIGN

A randomized controlled trial.

PARTICIPANTS AND SETTING

Eighty-two patients with heart failure were recruited from a cardiovascular outpatient department at a teaching hospital in northern Taiwan.

METHODS

Participants were randomly assigned to the intervention (n = 41) or control group (n = 41). The intervention group participated in a 4-week self-regulation programme, including one 20-to-30-min, face-to-face individual self-regulation education session and 15- to 20-min telephone follow-up counselling sessions twice per week for four weeks. The control group received only routine outpatient care. Self-care behaviour was measured by the Self-Care of Heart Failure Index at baseline, 4 weeks and 8 weeks after patients were enroled.

RESULTS

The intervention group reported improvements in self-care behaviours, including self-maintenance and self-confidence subscale scores, after four weeks of the self-regulation programme. In contrast, the control group showed no significant differences. Compared with the control group, the intervention group exhibited significantly greater improvements in self-care maintenance (B = 3.74, p = 0.01), self-care management (B = 6.33, p = 0.004), and self-care confidence (B = 5.15, p = 0.003) at four weeks but showed significantly greater improvements only in self-care management (B = 6.97, p = 0.03) and self-care confidence (B = 6.24, p = 0.001) at 8 weeks.

CONCLUSIONS

This study confirmed that a self-regulation programme could effectively improve self-care behaviour in patients with heart failure. Further studies with multicentre randomized controlled trials and larger populations of heart failure patients are necessary to evaluate the effect of this self-regulation programme in various regions and countries. Tweetable abstract: A home-based self-regulation programme could effectively improve self-care behaviour in patients with heart failure.

Theory-guided interventions for Chinese patients to adapt to heart failure: A quasi-experimental study

Objectives

To examine the effects of the Roy Adaptation Model-based interventions on adaptation in persons with heart failure.

Methods

A quasi-experimental study was conducted in Hangzhou, China, from March 2018 to November 2019. A convenience sample of 112 participants with heart failure from a multi-campus hospital was enrolled. Participants were allocated into an intervention group (n = 55) and a control group (n = 57) according to their hospitalized campus. A culturally-tailored care plan intervention based on the Roy Adaptation Model was performed in the intervention group. The control group received bedside patient education and a regular booklet for HF home care before discharge. Heart ultrasound, Minnesota Living with Heart Failure Questionnaire (MLHFQ), a knowledge survey, Self-care Heart failure Index (SCHFI), and Coping and Adaptation Processing Scale-Short Form (CAPS-SF) were used to measure patients’ levels of adaptation of physical function, self-concept, role function, and interdependence at baseline and six months after discharge.

Results

Ninety-one participants with complete data, 43 in the intervention group and 48 in the control group, were included in the analysis for the primary endpoints and showed adaptive improvement trends. Most patients in the intervention group completed 60% or more of the given interventions. At the sixth month after discharge, compared with the control group, the intervention group had improved adaptive behaviors showing higher scores of the MLHFQ (70.90 ± 22.45 vs. 54.78 ± 18.04), heart failure-related knowledge (13.79 ± 2.45 vs. 10.73 ± 4.28), SCHFI maintenance (57.67 ± 13.22 vs. 50.35 ± 10.88), and CAPS-SF (40.23 ± 4.36 vs. 38.27 ± 2.60) at the six-month follow-up (P ＜ 0.05). There were no significant differences between the two groups in the scores of left ventricular ejection fraction, scores of SCHFI management and SCHFI confidence subscales (P > 0.05).

Conclusions

The findings reported evidence of positive adaptation in patients with heart failure, indicating that the Roy Adaptation Model is an effective guide for developing an implemented framework for the nursing practice of the patients. The culturally-tailored care plan intervention is helpful to improve adaptation of patients with heart failure.

[Comparative analysis of self-care assessment scales in patients with chronic heart failure, advantages and disadvantages]

Aim To compare Russian versions of the scales for assessment of self-care ability in patients with chronic heart failure (CHF), European Heart Failure Self-Care Behavior Scale (EHFScBS_9) and The Self-Сare of Heart Failure Index (SCHFI, version 6.2).Materials and methods Assessment of the self-care ability was performed with Russian versions of EHFScBS_9 and SCHFI (version 6.2) scales in 130 patients with NYHA functional class II-IV CHF primarily of ischemic origin (78.5 %). Mean age of patients was 63.2±9.6 years; most of the patients were men (n=92; 70.8 %). Patients were managed in accordance with effective guidelines ESC / HFA 2016 and Russian guidelines 2018.Results Along with an increase in SСHFI scores, a decrease in EHFScBS_9 scores was observed (r= -0.31, p&lt;0.001). The patients participating in the study showed a low self-care ability at baseline according to results of both scales.Conclusion The presence of certain differences between the study scales does not exclude a possibility of using them alone or together for more detailed assessment of the self-care ability.

How do self-care maintenance, self-care monitoring, and self-care management affect glycated haemoglobin in adults with type 2 diabetes? A multicentre observational study

PURPOSE

To evaluate how self-care maintenance, self-care monitoring, and self-care management affect glycated haemoglobin in type 2 diabetes mellitus patients and to set cut-off points of the Self-Care of Diabetes Inventory scales using glycated haemoglobin as outcome of interest.

METHODS

A secondary analysis of a previous multicentre observational cross-sectional study was conducted. Overall, 540 adults with type 2 diabetes mellitus confirmed diagnosis were involved. Socio-demographic and clinical data were collected. Self-care maintenance, self-care monitoring, and self-care management were measured by the Self-Care of Diabetes Inventory. Linear regression models were performed to assess the relationship between self-care maintenance, self-care monitoring, and self-care management and glycated haemoglobin. Receiver operating characteristics curves were carried out to identify the best cut-off score for each self-care scale considering glycated haemoglobin >7% as outcome of interest.

RESULTS

Self-care monitoring and self-care management were associated to glycated haemoglobin in both patients without (self-care monitoring p = 0.0008; self-care management p = 0.0178) and with insulin therapy (self-care monitoring p = 0.0007; self-care management p = 0.0224). Self-care maintenance was associated to glycated haemoglobin in patients without insulin therapy (p = 0.0118). Cut-off scores providing the best performance were 70 points for self-care maintenance and self-care monitoring, and 60 points for self-care management.

CONCLUSIONS

Self-care maintenance, self-care monitoring, and self-care management differently affect glycated haemoglobin in patients with type 2 diabetes mellitus. Clinicians could implement tailored interventions to improve glycaemic control considering the lacking area of self-care.

Patterns of Heart Failure Dyadic Illness Management: The Important Role of Gender

BACKGROUND

The ways in which patients with heart failure (HF) and their care partners work together to manage HF are often overlooked.

OBJECTIVE

The aim of this study was to identify and compare different patterns of HF dyadic illness management.

METHODS

This was a secondary analysis of data on HF dyads. Heart failure management was measured using patient and care partner versions of the Self-Care of HF Index and European HF Self-care Behavior Scale. Latent class modeling was used to identify patterns of HF dyadic management.

RESULTS

The mean age of the 62 patients and their care partners was 59.7 ± 11.8 and 58.1 ± 11.9 years, respectively. A majority of patients (71.0%) had class III/IV HF, and a majority of the couples (95.2%) were married. Two distinct dyadic patterns were observed, 1 collaborative management type (n = 42, 67.7%) and 1 autonomous management type (n = 20, 32.3%). Dyads in the autonomous pattern were mostly female patients with male care partners; patients in this pattern also were more anxious and depressed, and reported worse relationship quality compared with collaborative dyads.

CONCLUSION

There is an engendered spectrum of collaboration in how HF patient-care partner dyads work together to manage HF that needs to be considered in clinical care and research.

Exploring the potential of acceptance and commitment therapy model in self-care behaviour in persons with heart failure

Aim

This study examined the interaction among cognitive fusion, mindfulness and committed action on the self-care behaviour in person with heart failure as guided by the acceptance and commitment therapy model.

Design

An exploratory cross-sectional design was used.

Method

Participants with heart failure from in-patients setting (N = 165) were recruited from two major regional hospitals. Data were collected using self-report questionnaires of the study variables and demographic characteristics. Data were analysed using Hayes SPSS process macros.

Results

Based on the acceptance and commitment therapy model propositions, all main and interaction effects, except for cognitive fusion, were significant. The current study showed that the main effect of the study variables on self-care behaviour was insufficient and adding complex interactions between these variables improved the model fit, as it was suggested by the acceptance and commitment therapy model.

SCHFI 6.2 Self-Care Confidence Scale - Brazilian version: psychometric analysis using the Rasch model

OBJECTIVE

to evaluate the psychometric properties of the Self-Care Confidence Scale in heart failure in the Brazilian version of the Self Care Heart Failure Index, version 6.2, using the Rasch model criteria.

METHOD

secondary study, of psychometric analysis, using the Rasch model, of the six items of the scale. The sample consisted of 409 patients with heart failure undergoing outpatient treatment [mean age 57.9 (standard deviation = 11.6) years, 54.8% male].

RESULTS

of the total of six items, one ("De maneira geral, você está confiante sobre estar livre dos sintomas de insuficiência cardíaca?") presented maladjustment to the model (Infit = 1.84 and Outfit = 1.99). After the exclusion of this item, the others showed a good fit, composed one dimension and explained 55% of the variance in the data; the categories of response to the items were adequate, the values of separation and reliability of person were 2.13 and 0.82, respectively, and Cronbach's alpha was 0.87. Items of extreme difficulty were identified and there is no differential functioning of the items in relation to sex.

CONCLUSION

with the exclusion of the first item, the Self-Care Confidence Scale showed good psychometric properties, with caution in interpreting the results of the six-item scale.

The role of health literacy, depression, disease knowledge, and self-efficacy in self-care among adults with heart failure: An updated model

BACKGROUND

Patients with inadequate health literacy and heart failure face high healthcare costs, more hospitalizations, and greater mortality. To address these negative consequences, patients need to improve heart failure self-care. Multiple factors may influence self-care, but the exact model by which they do so is not fully understood.

OBJECTIVES

The objective of this study was to examine a model exploring the contribution of health literacy, depression, disease knowledge, and self-efficacy to the performance of heart failure self-care.

METHODS

Using a cross-sectional design, patients were recruited from a heart failure clinic and completed validated assessments of their cognition, health literacy, depression, knowledge, self-efficacy and self-care. Patients were separated into two groups according to their health literacy level: inadequate/marginal and adequate. Differences between groups were assessed with an independent t-test. Hypothesized paths and mediated relationships were estimated and tested using observed variable path analysis.

RESULTS

Participants (n = 100) were mainly male (67%), white (93%), and at least had a high school education (85%). Health literacy was associated with disease knowledge (path coefficient=0.346, p = 0.002), depression was negatively associated with self-efficacy (path coefficient=-0.211, p = 0.037), self-efficacy was positively associated with self-care (path coefficient=0.402, p<0.0005), and there was evidence that self-efficacy mediated the link between depression and self-care. There was no evidence of: mediation of the link between health literacy and self-care by knowledge or self-efficacy; positive associations between knowledge and self-efficacy or self-care; or mediation of the disease knowledge and self-care relationship by self-efficacy. Further, depression was associated with self-care indirectly rather than also directly as hypothesized.

CONCLUSIONS

Self-efficacy and depression are associated with heart failure self-care. Data generated from the model suggest that healthcare professionals should actively engage all patients to gain self-efficacy and address depression to positively affect heart failure self-care.

The mediating effect of resilience on the relationship between Type D personality and self-care behavior in patients with heart failure

AIM

There have been few studies done looking at the relationship between resilience, Type D personality, and self-care behavior in patients with heart failure. The purpose of this study was to identify the mediating effect of resilience on the relationship between Type D personality and self-care behavior in patients with heart failure.

METHODS

The subjects consisted of a sample of 90 heart failure patients aged ≥20 years who visited the cardiology outpatient clinic in the Chungbuk area of South Korea.

RESULTS

Among 90 patients, 49 subjects (54.0%) were classified as Type D personality, who exhibited statistically significant differences in resilience and self-care behavior (p < .001). A statistically significant correlation was also observed between self-care behavior score and resilience score (p < .01). The resilience had full mediation effects on the relationship between Type D personality and self-care behavior. In other words, the higher their resilience, the better their self-care behavior.

CONCLUSIONS

The study showed that resilience and Type D personality have important effects on self-care behavior.

Feasibility of an Emotion Regulation Intervention for Patients in Cardiac Rehabilitation

Cardiac rehabilitation is important to improve physical activity and reduce cardiovascular disease risk factors among people who have experienced a major cardiac event. However, poor emotion regulation can make it difficult to change cardiovascular risk factors. The purpose of this article was to assess the feasibility of the Regulating Emotions to improve Nutrition Exercise and reduce Stress (RENEwS) intervention, an education program aimed at improving emotion regulation strategies among patients in cardiac rehabilitation. A total of 14 cardiac rehabilitation patients (mean age 61 years) enrolled in five weekly RENEwS sessions. Qualitative analysis of participants' comments was used to assess eight elements of feasibility. In total 57% of participants completed the intervention. Participants thought the intervention was feasible, with strengths in the areas of acceptability, demand, adaptation, integration, and implementation. Other comments regarding practicality, expansion, and perceived efficacy provide guidance for intervention refinement.

Cross-Cultural Adaptation, Validity, and Reliability of the Arabic Version of the Self-care of Hypertension Inventory Scale Among Older Adults

BACKGROUND

Self-care is considered as the best method of blood pressure control. Because the prevalence of hypertension in Arab countries is high and continuously increasing through the years, more attention is needed to evaluate patients' self-care for hypertension, to enable further studies to develop the appropriate intervention. The Self-care of Hypertension Inventory (SC-HI) is a scale that has been developed to measure the maintenance, monitoring, and management of a person with hypertension.

OBJECTIVE

The aim of this study was to assess the psychometric properties of the Arabic version of the SC-HI scale among older adults.

METHODS

A cross-cultural adaptation process was used, where structural validity was assessed through factor analysis and interobserver agreement using Cohen κ. The reliability of internal consistency was determined through Cronbach's α and scale item correlation. Test-retest examined the interclass correlation and was tested by paired t test.

RESULTS

The mean age of our sample is 63 ± 7.8 years, and most were educated (illiterate patients, 14%). Some modification was done for the scale items. Item-level content validity index ranged between 0.85 and 1, and average scale-level content validity was 0.96. Interobserver adjustment showed high agreement. Cronbach's α was 0.89. Test-retest reliability showed no differences (t = -0.298, P = 0,767), and interclass correlation was 0.85 (95% confidence interval, 0.078-0.90; P < .01). Factor analysis extracted 2, 3, and 1 signal factors for maintenance, management, and confidence subscales, respectively.

CONCLUSION

The adapted Arabic version of SC-HI scale is shown to be valid and reliable among older adults. Further studies are need for further reliability analyses among large groups from various Arab countries.

Executive dysfunction is associated with self-care confidence in patients with heart failure

AIM

To explore differences in self-care maintenance, management and confidence levels between American heart failure (HF) patients with and without executive dysfunction.

BACKGROUND

Evidence indicates some aspect of cognitive impairment is prevalent in up to 75% of the HF patient population. Moreover, cognitive impairment has been identified as a barrier to adequate self-care contributing to poor outcomes. There is limited understanding of the role executive function, a domain of cognitive performance, has on self-care behaviors for patients with HF.

METHOD

This secondary analysis examined the role of executive function, measured by the Clock Drawing Test (CDT), in relation to self-care measures. The Self Care of Heart Failure Index v6.2 (SCHFI v6.2) was used to measure self-care maintenance, management, and confidence.

RESULTS

Participants had a mean age of 75.1 ± 12.5 years, identified as male (59.4%), with New York Heart Association (NYHA) class III (57.3%). Executive function impairment was present in 28% of the sample. Comparison of self-care maintenance and management scores between the two groups were not significant. However, participants with executive dysfunction demonstrated an average self-care confidence score of 48.6 ± 23.3, while participants with no executive function impairment demonstrated a higher average self-care confidence score of 61.5 ± 18.4. Differences in self-care confidence scores between the groups were statistically significant (p = .014).

CONCLUSIONS

HF self-care confidence is considered a moderator of self-care behaviors. Understanding the influence executive function has on self-care confidence may lead to a better understanding of those needing greater support with self-care behaviors.

Effectiveness of an avatar educational application for improving heart failure patients' knowledge and self-care behaviors: A pragmatic randomized controlled trial

AIM

To evaluate the effectiveness of education using avatars for improving patients' heart failure knowledge and self-care.

BACKGROUND

A lack of knowledge and self-care contributes to poor outcomes and rehospitalization for people with heart failure.

DESIGN

A multi-centred, non-blinded pragmatic randomized controlled trial.

METHODS

Heart failure patients were randomly assigned to intervention (avatar education application) or usual care groups. Participants were followed up at baseline, 30 and 90 days. ANCOVA was used to compare the scores of heart failure knowledge and self-care, between the two groups. Fisher's exact test was used to compare the two groups' heart failure-cause readmission. Bivariate exact binary logistic regression was used to identify the predictors associated with baseline levels of knowledge.

RESULTS

A total of 36 participants were recruited (between October 2018 - March 2019). The mean age of participants was 67.5 (SD 11.3) years. At enrolment, approximately half (47.2%) have been living with Heart Failure for over 5 years. Two groups were comparable at baseline in their demographic and clinical characteristics. At 90 days, the intervention group participants had a higher increase in knowledge score on the Dutch Heart Failure Knowledge Scales compared with the control group (22.2% versus 3.7% P = .002, partial η²  = 0.262, 95% CI -2.755 to -0.686). There was no between-group difference observed at 30- or 90-day follow-up, on self-care behaviour (Self-care of heart failure index) or healthcare use. Overall satisfaction with the avatar app was 91.3%.

CONCLUSION

The addition of a co-designed avatar app to usual care improved knowledge in our group of Heart Failure participants at 30 days and continued to increase up to 90 days. The results suggest that our avatar app was perceived as an enjoyable and engaging means of delivering critical knowledge and self-care information.

IMPACT

Heart failure is associated with poor clinical outcomes (i.e., readmission rates and mortality rate) and substantial economic burden. The effectiveness of Heart Failure patient education using avatar have not been investigated previously. In this study, the avatar app improved knowledge and self-care behaviours. This innovation could be used at the bedside, at home by nurses, patients and families.

Self-care behavior: a new insight of the role of impulsivity into decision making process in persons with heart failure

Background

Self-care behavior has been reported to be below optimum in persons with heart failure, while the underlying decision making is not well understood. The Hot/Cool System model is a psychological model that may have potential applications in decision making process in persons with heart failure. The aim of this study was to examine the decision making process in self-care behavior in persons with heart failure in the light of the Hot/Cool System model.

Methods

We used the Hoot/Cool System Model to guide this study. Participants with heart failure from in-patients setting (N = 107) were recruited. Data were collected using self-report questionnaires. Moderated mediation analysis was used to study complex relationships among study variables.

Results

The current study showed that impulsivity and perceived stress were negatively associated with self-care behavior. The results also showed that self-care confidence and impulsivity significantly predict self-care maintenance. The moderated mediation analysis revealed that self-care confidence mediated the relationship between impulsivity and self-care maintenance at lower levels of perceived stress, but not at higher levels of perceived stress.

Conclusion

Our findings revealed that persons with heart failure tend to make impulsive choices that may negatively affect disease progression under higher levels of perceived stress. This study provides foundational knowledge regarding the decision making process in persons with heart failure.

Association between sleep quality and self-care in adults with heart failure: A systematic review

BACKGROUND

Sleep disturbance is one of the most common symptoms among heart failure patients. Sleep disturbance reduces quality of life and leads to higher rates of mortality. It may affect the ability of patients to perform adequate self-care. Although some research has evaluated the association between sleep quality and heart failure self-care, a synthesis of the most recent available evidence is lacking.

AIMS

This systematic review aimed to assess the association between sleep quality and self-care in adults with heart failure.

METHODS

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses methodology was used. Medline, CINAHL, PsycINFO and SCOPUS were searched. Observational, case-control and cohort studies were considered. The quality of the studies was evaluated with the Joanna Briggs Institute's Critical Appraisal Tools.

RESULTS

Six articles were included. Association between sleep quality and self-care was reported by three studies. One of these did not find an association between sleep disturbance and heart failure self-care, while the other two studies did. An association between sleep quality and medication adherence was reported by three studies. All three of these studies found associations between these two variables. Studies have measured similar but different constructs. Two studies assessed sleep quality, while four other studies measured excessive daytime sleepiness. Half of the studies examined self-care, while the other half measured medication adherence.

CONCLUSIONS

Although the evidence should be strengthened, sleep quality seems to affect self-care in heart failure patients. The mechanism underlying the effect of sleep quality on heart failure self-care remains unclear. Future longitudinal interaction analyses could be useful to clarify this mechanism.

The value of social practice theory for implementation science: learning from a theory-based mixed methods process evaluation of a randomised controlled trial

Background

Although there is trial evidence that complex interventions are effective for the self-management of heart failure, little evidence supports their effectiveness in routine practice. We used Social Practice Theory to guide a Type 1 Hybrid Trial: a mixed methods process evaluation of a complex intervention for heart failure. The objective of this paper is to explore the value of Social Practice Theory for implementation science.

Methods

Social Practice Theory informed a mixed methods process evaluation of a multi-centre randomised controlled trial of a 12 week home-based intervention to optimise self-care support for people with heart failure and their caregivers - Rehabilitation EnAblement in Chronic Heart Failure (REACH-HF). Interviews were conducted with 19 people with heart failure and 17 caregivers at 4 months and 12 months after recruitment into the trial. Cases were constructed at the level of the individual, couple, facilitator and centre; and included multi-modal process and outcome data. Evaluative coding and subsequent within- and cross-case analyses enabled the development of a typology of relationships linking fidelity of intervention delivery and tailoring of content to individual needs and concerns. Social Practice Theory was used to interrogate the relationships between elements of the intervention and their implementation.

Results

Of 216 trial participants, 107 were randomised to the intervention (REACH-HF plus usual care). The intervention was most effective when fidelity was high and delivery was tailored to the individual’s needs, but less effective when both tailoring and fidelity were low. Theory-based analysis enabled us to model complex relationships between intervention elements (competencies, materials and meanings) and social context. The findings illustrate how intervention fidelity and tailoring are contextual and how the effectiveness of the REACH-HF intervention depended on both optimal alignment and implementation of these elements.

Conclusion

The study demonstrates the utility of theory-based analysis which integrates data from multiple sources to highlight contexts and circumstances in which interventions work best. Social Practice Theory provides a framework for guiding and analysing the processes by which a complex intervention is evaluated in a clinical trial, and has the potential to guide context-specific implementation strategies for clinical practice.

Effects of illness representation-focused patient education on illness representations and self-care in patients with heart failure: A randomised clinical trial

AIMS AND OBJECTIVES

To examine the effect of an illness representation-focused patient education intervention on illness representations and self-care behaviours in patients with heart failure 3 months after discharge from the hospital.

BACKGROUND

Few intervention studies have examined the effect of illness representation-focused interventions on illness representations and self-care in patients with heart failure.

DESIGN

A randomised clinical trial based on the Consolidated Standard of Reporting Trials-CONSORT 2010-guidelines was employed. The Clinical Trial Registry number is TCTR20190903002.

METHODS

One hundred and seven participants were randomly assigned to 2 groups, and 62 participants (n = 30 in the intervention group and n = 32 in the usual care group) completed the baseline and one- and three-month postdischarge follow-up assessments. The instruments included the Survey of Illness Beliefs in Heart Failure and the Self-care of Heart Failure Index. The intervention group received illness representation-focused patient education while hospitalised and telephone follow-ups after discharge. Data were analysed with linear mixed-effects model analysis.

RESULTS

The 107 participants had a mean age of 62.17 years and a mean left ventricular ejection of 53.03%. At baseline, the two groups tended to have accurate illness beliefs but insufficient self-care confidence and self-care maintenance. The analysis showed no significant differences between groups in the illness representation total scores, dimension scores or self-care maintenance scores but did show a significant difference in the self-care confidence scores (F = 3.42, p < .05) over the three months.

CONCLUSION

The study did not show an effect of the intervention on illness representations or self-care maintenance behaviours. However, the intervention did maintain participants' self-care confidence three months after discharge.

RELEVANCE TO CLINICAL PRACTICE

It is necessary to conduct long-term follow-ups of patients' illness representations, discuss the implementation of self-care behaviours with patients, enhance patients' self-care confidence, and involve family members or caregivers in self-care practices when needed.

Development and feasibility testing of an interactive avatar education application for education of patients with heart failure

Background/aims

Heart failure self-care is important for achieving optimal patient outcomes. Interactive information technology has been shown to enhance self-care knowledge and behaviours. This study aimed to codevelop and evaluate with consumers an avatar app for teaching heart failure self-care.

Methods

Consumer participation and pre-post test methods.

Findings

A total of six heart failure patients, two patients' family members and 15 heart failure clinicians and app developers participated in the development of the app. Overall, 13 people completed the app's feasibility testing and demonstrated a significant improvement in heart failure knowledge (P=0.020), self-care maintenance (P=0.027) and self-care confidence (P=0.002). Self-care management did not improve significantly (P=0.113) and satisfaction with learning using the app was very high (90%).

Conclusions

The codevelopment approach used in this project resulted in a high level of user satisfaction. Consumers felt the app was a very feasible mechanism of heart failure education delivery.

Motivational interviewing to improve self-care in heart failure patients (MOTIVATE-HF): a randomized controlled trial

AIMS

Self-care, an essential component of heart failure (HF) treatment, is inadequate in most patients. We evaluated if motivational interviewing (MI) (i) improves patient self-care maintenance (primary endpoint; e.g. taking medications), self-care management (e.g. responding to symptoms) and self-care confidence (or self-efficacy) 3 months after enrolment; (ii) changes self-care over 1 year, and (iii) augments patient self-care if informal caregivers are involved.

METHODS AND RESULTS

Parallel randomized controlled trial (1:1:1). A sample of 510 patients (median 74 years, 58% male) and caregivers (median 55 years, 75% female) was randomized to Arm 1 (MI only for patients), Arm 2 (MI for patients and caregivers), or Arm 3 (usual care). The intervention in Arms 1 and 2 consisted of one face-to-face MI session with three telephone contacts. Self-care was evaluated with the Self-Care of HF Index measuring self-care maintenance, management, and confidence. Scores on each scale range from 0 to 100 with higher scores indicating better self-care; ≥70 is considered adequate. At 3 months, self-care maintenance improved 6.99, 7.42 and 2.58 points in Arms 1, 2, and 3, respectively (P = 0.028). Self-care maintenance was adequate in 18.4%, 19.4%, and 9.2% of patients in Arms 1, 2 and 3, respectively (P = 0.016). Over 1 year, self-care maintenance, management, and confidence scores in Arms 1 and 2 were significantly higher than in Arm 3 in several follow-ups. Over 1 year, Arm 2 had the best scores in self-care management.

CONCLUSIONS

MI significantly improved self-care in HF patients. Including caregivers may potentiate the effect, especially in self-care management. ClinicalTrial.gov, identifier: NCT02894502.

Perceived Control Predicts Symptom Status in Patients With Heart Failure

BACKGROUND

Symptom status is an important indicator of disease progression in patients with heart failure (HF). Perceived control is a target of most self-care interventions and is associated with better outcomes in HF; however, little is known about the relationship between perceived control and symptom status in patients with HF.

OBJECTIVE

The aims of this study were to (1) determine the relationship of perceived control to HF symptom status and (2) examine the associations of perceived control to self-care and of self-care to symptom status.

METHODS

A total of 115 patients with HF were included. Data on symptom status (Memorial Symptom Assessment Scale-HF), perceived control (Control Attitudes Scale-Revised), and self-care (Self-Care of Heart Failure Index) were collected. Other covariates included were age, gender, New York Heart Association class, comorbidity burden, and depressive symptoms. Multiple regression analyses were performed to analyze the data.

RESULTS

Lower perceived control predicted worse symptom status after controlling for covariates (P = .009). Other covariates predictive of worse symptom status were younger age, New York Heart Association class III/IV, and higher levels of depressive symptoms. Higher levels of perceived control were associated with better self-care (P = .044). Better self-care was associated with better symptom status (P = .038).

CONCLUSIONS

Lower levels of perceived control were independently associated with worse symptom status in patients with HF. Intervention strategies targeting perceived control should be tested to determine whether they could improve symptom status.

Psychometric Testing of the Revised Self-Care of Heart Failure Index

BACKGROUND

Self-care is essential in people with chronic heart failure (HF). The process of self-care was refined in the revised situation specific theory of HF self-care, so we updated the instrument measuring self-care to match the updated theory. The aim of this study was to test the psychometric properties of the revised 29-item Self-Care of Heart Failure Index (SCHFI).

METHODS

A cross-sectional design was used in the primary psychometric analysis using data collected at 5 sites in the United States. A longitudinal design was used at the site collecting test-retest data. We tested SCHFI validity with confirmatory factor analysis and predictive validity in relation to health-related quality of life. We tested SCHFI reliability with Cronbach α, global reliability index, and test-retest reliability.

RESULTS

Participants included 631 adults with HF (mean age, 65 ± 14.3 years; 63% male). A series of confirmatory factor analyses supported the factorial structure of the SCHFI with 3 scales: Self-Care Maintenance (with consulting behavior and dietary behavior dimensions), Symptom Perception (with monitoring behavior and symptom recognition dimensions), and Self-Care Management (with recommended behavior and problem-solving behavior dimensions). Reliability estimates were 0.70 or greater for all scales. Predictive validity was supportive with significant correlations between SCHFI scores and health-related quality-of-life scores.

CONCLUSIONS

Our analysis supports validity and reliability of the SCHFI v7.2. It is freely available to users on the website: www.self-care-measures.com.

Depression and self-care in older adults with multiple chronic conditions: A multivariate analysis

AIMS

To investigate the relationship between depression and self-care behaviours in older individuals with multimorbidity.

DESIGN

Cross-sectional study. Data were collected between April 2017 - June 2019.

METHODS

Patients were enrolled from community and outpatient settings and included if they were ≥65 years, affected by heart failure, diabetes mellitus or chronic obstructive pulmonary disease and at least another chronic condition. They were excluded if they had dementia and/or cancer. Patient Health Questionnaire-9 was used to measure depression and Self-Care of Chronic Illness Inventory was used to measure self-care maintenance, monitoring, and management. The relationship between depression and self-care was evaluated by performing two sets of univariate analyses, followed by multivariate and step-down analyses. The second set was performed to control for the number of chronic conditions, age, and cognitive function.

RESULTS

The sample (N = 366) was mostly female (54.2%), with a mean age of 76.4 years. Most participants (65.6%) had mild to very severe depressive symptoms. Preliminary analysis indicated a significant negative association between depression and self-care maintenance and monitoring and a significant negative association between depression and multivariate self-care. Step-down analysis showed that self-care maintenance was the only dimension negatively associated with depression, even after controlling for the number of chronic conditions, age, and cognitive function.

CONCLUSION

In multimorbid populations, depression is more likely to be associated with self-care maintenance than the other self-care dimensions. Therefore, self-care maintenance behaviours (e.g., physical activity and medication adherence) should be prioritized in assessment and focused on when developing interventions targeting depressed older adults with multimorbidity.

IMPACT

The results of this study may help guide clinical practice. In patients with depressive symptoms, self-care maintenance behaviours should be assessed first, as a potential first indicator of poor self-care.

A Smartphone App for Self-Management of Heart Failure in Older African Americans: Feasibility and Usability Study

Background

Mobile health (mHealth) apps are dramatically changing how patients and providers manage and monitor chronic health conditions, especially in the area of self-monitoring. African Americans have higher mortality rates from heart failure than other racial groups in the United States. Therefore, self-management of heart failure may improve health outcomes for African American patients.

Objective

The aim of the present study was to determine the feasibility of using an mHealth app, and explore the outcomes of quality of life, including self-care maintenance, management, and confidence, among African American patients managing their condition after discharge with a diagnosis of heart failure.

Methods

Prior to development of the app, we conducted qualitative interviews with 7 African American patients diagnosed with heart failure, 3 African American patients diagnosed with cardiovascular disease, and 6 health care providers (cardiologists, nurse practitioners, and a geriatrician) who worked with heart failure patients. In addition, we asked 6 hospital chaplains to provide positive spiritual messages for the patients, since spirituality is an important coping method for many African Americans. These formative data were then used for creating a prototype of the app, named Healthy Heart. Specifically, the Healthy Heart app incorporated the following evidence-based features to promote self-management: one-way messages, journaling (ie, weight and symptoms), graphical display of data, and customized feedback (ie, clinical decision support) based on daily or weekly weight. The educational messages about heart failure self-management were derived from the teaching materials provided to the patients diagnosed with heart failure, and included information on diet, sleep, stress, and medication adherence. The information was condensed and simplified to be appropriate for text messages and to meet health literacy standards. Other messages were derived from interviews conducted during the formative stage of app development, including interviews with African American chaplains. Usability testing was conducted over a series of meetings between nurses, social workers, and computer engineers. A pilot one-group pretest-posttest design was employed with participants using the mHealth app for 4 weeks. Descriptive statistics were computed for each of the demographic variables, overall and subscales for Health Related Quality of Life Scale 14 (HQOL14) and subscales for the Self-Care of Heart Failure Index (SCHFI) Version 6 using frequencies for categorical measures and means with standard deviations for continuous measures. Baseline and postintervention comparisons were computed using the Fisher exact test for overall health and paired t tests for HQOL14 and SCHFI questionnaire subscales.

Results

A total of 12 African American participants (7 men, 5 women; aged 51-69 years) diagnosed with heart failure were recruited for the study. There was no significant increase in quality of life (P=.15), but clinically relevant changes in self-care maintenance, management, and confidence were observed.

Conclusions

An mHealth app to assist with the self-management of heart failure is feasible in patients with low literacy, low health literacy, and limited smartphone experience. Based on the clinically relevant changes observed in this feasibility study of the Healthy Heart app, further research should explore effectiveness in this vulnerable population.

Patient and caregiver contributions to self-care in multiple chronic conditions: A multilevel modelling analysis

BACKGROUND

Multiple chronic conditions (MCC) are highly prevalent worldwide, especially among older populations. Patient self-care and care partner (or caregiver) contributions to self-care are recommended to reduce the impact of MCC and improve patients' outcomes.

OBJECTIVES

To describe patient self-care and care partner contributions to self-care and to identify determinants of patient self-care and care partner contributions to self-care at the patient and care partner level.

DESIGN

Multicentre cross-sectional study.

SETTING

Outpatient and community settings in Italy.

PARTICIPANTS

A sample of 340 patients with MCC and care partner dyads was recruited between 2017 and 2018.

METHODS

We measured patient's self-care and care partner contributions to self-care in dyads using the Self-care of Chronic Illness Inventory and the Caregiver Contribution to Self-care of Chronic Illness Inventory. To control for dyadic interdependence, we performed a multilevel modelling analysis.

RESULTS

Patients' and care partners' mean ages were 76.65 (± 7.27) and 54.32 (± 15.25), respectively. Most care partners were female and adult children or grandchildren. The most prevalent chronic conditions in patients were diabetes (74%) and heart failure (34%). Patients and care partners reported higher levels of self-care monitoring than self-care maintenance and management behaviours. Important patient clinical determinants of self-care included cognitive status, number of medications and type of chronic condition. Care partner determinants of self-care contributions included age, gender, education, perceived income, care partner burden, caregiving hours per week and the presence of a secondary care partner.

CONCLUSIONS

Our findings support the importance of taking a dyadic approach when focusing on patients with MCC and their care partners. More dyadic longitudinal research is recommended to reveal the modifiable determinants of self-care and the complex relationships between patients and care partners in the context of MCC.

Understanding the family care dyad: A comparison of two multilevel models

Although there has been increasing attention on a dyadic perspective of illness, contemporary dyadic research methods are still rarely utilized in cardiovascular disease. The focus of this paper is to describe the advantages of two types of multilevel dyadic models (the matched pairs model and the lesser known incongruence model). Data exemplars in a sample of heart failure family dyads are used to illustrate the distinct advantages of these two related multilevel dyadic models with particular emphasis on alignment with research questions. The more commonly known matched pairs model examines separate outcomes for each member of the dyad, controlling for the interdependent nature of the data. By re-parameterizing this model into a univariate dyadic outcomes model, researchers can address distinct, and sometimes more appropriate, research questions (e.g. incongruent appraisals of the illness experience). This paper promotes greater application of these methods in cardiovascular research to further understanding of the dyadic experience and more appropriately target interventions.

Outcomes of a Heart Failure Telemonitoring Program Implemented as the Standard of Care in an Outpatient Heart Function Clinic: Pretest-Posttest Pragmatic Study

Background

Telemonitoring (TM) can improve heart failure (HF) outcomes by facilitating patient self-care and clinical decisions. The Medly program enables patients to use a mobile phone to record daily HF readings and receive personalized self-care messages generated by a clinically validated algorithm. The TM system also generates alerts, which are immediately acted upon by the patients’ existing care team. This program has been operating for 3 years as part of the standard of care in an outpatient heart function clinic in Toronto, Canada.

Objective

This study aimed to evaluate the 6-month impact of this TM program on health service utilization, clinical outcomes, quality of life (QoL), and patient self-care.

Methods

This pragmatic quality improvement study employed a pretest-posttest design to compare 6-month outcome measures with those at program enrollment. The primary outcome was the number of HF-related hospitalizations. Secondary outcomes included all-cause hospitalizations, emergency department visits (HF related and all cause), length of stay (HF related and all cause), and visits to the outpatient clinic. Clinical outcomes included bloodwork (B-type natriuretic peptide [BNP], creatinine, and sodium), left ventricular ejection fraction, and predicted survival score using the Seattle Heart Failure Model. QoL was measured using the Minnesota Living with Heart Failure Questionnaire (MLHFQ) and the 5-level EuroQol 5-dimensional questionnaire. Self-care was measured using the Self-Care of Heart Failure Index (SCHFI). The difference in outcome scores was analyzed using negative binomial distribution and Poisson regressions for the health service utilization outcomes and linear regressions for all other outcomes to control for key demographic and clinical variables.

Results

Available data for 315 patients enrolled in the TM program between August 2016 and January 2019 were analyzed. A 50% decrease in HF-related hospitalizations (incidence rate ratio [IRR]=0.50; P<.001) and a 24% decrease in the number of all-cause hospitalizations (IRR=0.76; P=.02) were found when comparing the number of events 6 months after program enrollment with the number of events 6 months before enrollment. With regard to clinical outcomes at 6 months, a 59% decrease in BNP values was found after adjusting for control variables. Moreover, 6-month MLHFQ total scores were 9.8 points lower than baseline scores (P<.001), representing a clinically meaningful improvement in HF-related QoL. Similarly, the MLHFQ physical and emotional subscales showed a decrease of 5.4 points (P<.001) and 1.5 points (P=.04), respectively. Finally, patient self-care after 6 months improved as demonstrated by a 7.8-point (P<.001) and 8.5-point (P=.01) increase in the SCHFI maintenance and management scores, respectively. No significant changes were observed in the remaining secondary outcomes.

Conclusions

This study suggests that an HF TM program, which provides patients with self-care support and active monitoring by their existing care team, can reduce health service utilization and improve clinical, QoL, and patient self-care outcomes.

Heart failure self-care, factors influencing self-care and the relationship with health-related quality of life: A cross-sectional observational study

BACKGROUND

Self-care helps maintain health, prevents complications and improves the quality of life of patients living with heart failure (HF). Self-care is critical to HF management but has received limited attention in Nepal. Identification of the sociodemographic and clinical characteristics associated with self-care is crucial to tailoring appropriate self-care programs to improve health outcomes including patients' quality of life.

AIMS

The aims of this study were to describe self-care including the factors influencing self-care and the relationship between self-care and health-related quality of life in patients living with HF in Kathmandu, Nepal.

METHODS

We used a cross-sectional observational study design to measure self-care maintenance, self-care management, and self-care confidence using the Nepali Self-Care of Heart Failure Index. To analyze data, we used descriptive statistics, bivariate associations and regression modeling.

RESULTS

We recruited 221 patients with HF: mean age 57.5 ± 15.76 years, 62% male. The results in this sample indicated poor self-care maintenance (38.5 ± 11.56), management (45.7 ± 15.14), and confidence (40.9 ± 16.31). Patients with higher education were associated with higher self-care maintenance and management. Living alone and a better New York Heart Association functional classification for HF were related to higher self-care confidence. Higher social support was associated with better self-care. Self-care confidence was an independent predictor of self-care maintenance, management and health-related quality of life on adjusted analyses.

CONCLUSION

Self-care was limited among patients living with HF in Nepal yet was associated with better quality of life. The study identified various sociodemographic and clinical factors related to self-care, which could be crucial while developing self-care interventions.

Testing the Effect of a Home Health Heart Failure Intervention on Hospital Readmissions, Heart Failure Knowledge, Self-Care, and Quality of Life

For older adults, heart failure (HF) has the highest 30-day hospital readmission rate of any chronic illness. Despite research into strategies to reduce readmissions, no single program has emerged as sustainable. The purpose of the current study was to test a researcher-developed home health nurse HF intervention (CareNavRN^™) on 30-day readmission rates, HF knowledge, self-care, and quality of life (QOL) among 40 older adults transitioning home. Home health nurses received specialized HF training and visited patients once per week at home for 4 weeks. The control group (n = 21) had six readmissions (29%) and the intervention group (n = 19) had three readmissions (16%); however, the results were underpowered and statistically nonsignificant. Pre-/post-surveys demonstrated significant improvement in HF knowledge (p = 0.043), self-care confidence (p = 0.003), and QOL (p < 0.001) in the intervention group. CareNavRN is a promising approach to improve outcomes during transition from hospital to home for patients without access to a comprehensive disease management program.

Symptom perception in heart failure: a scoping review on definition, factors and instruments

BACKGROUND

Symptom perception in heart failure has been identified as crucial for effective self-care that is a modifiable factor related to decreased hospital readmission and improved survival.

AIMS

To review systematically the heart failure symptom perception literature and synthesise knowledge on definition, description, factors and instruments.

METHODS

We conducted a scoping review including studies reporting patient-reported symptom perception in adults with heart failure. Structured searches were conducted in Medline, PubMed, Embase, CINAHL, PsychINFO, Web of Science, Cochrane, JBI and grey literature. Two authors independently reviewed references for eligibility. Data were charted in tables and results narratively summarised.

RESULTS

The search yielded 3057 references, of which 106 were included. The definition of heart failure symptom perception comprised body listening, monitoring signs, recognising, interpreting and labelling symptoms, and furthermore awareness of and assigning meaning to the change. Symptom monitoring, recognition and interpretation were identified as challenging. Symptom perception facilitators include prior heart failure hospitalisation, heart failure self-care maintenance, symptom perception confidence, illness uncertainty and social support. Barriers include knowledge deficits, symptom clusters and lack of tools/materials. Factors with inconsistent impact on symptom perception include age, sex, education, experiences of living with heart failure, comorbidities, cognitive impairment, depression and symptom progression. One instrument measuring all dimensions of heart failure symptom perception was identified.

CONCLUSION

Heart failure symptom perception definition and description have been elucidated. Several factors facilitating or hampering symptom perception are known. Further research is needed to determine a risk profile for poor symptom perception - which can then be taken into consideration when supporting heart failure self-care.

Impact of Self-Efficacy Strategies Education on Self-Care Behaviors among Heart Failure Patients

Background: Self-efficacy in self-care behaviors is an effective framework for measuring patients' degree of ability to perform self-care behaviors that significantly affect their recovery process and quality of life. This study was designed to investigate the effects of education based on self-efficacy strategies on self-care behaviors in heart failure patients. Methods: A semi-experimental study was conducted on 80 heart failure patients divided into 2 equal groups of test and control. The intervention group received three 60-minute practical and theoretical training sessions based on self-care and self-efficacy strategies, while the control group received the usual care services. Self-care behaviors and self-efficacy were evaluated before training, shortly after training, and 3 months after the training program using the Sullivan self-efficacy questionnaire for heart failure patients and the European self-care behaviors questionnaires. Results: The mean age of the patients was 55.00±8.48 and 51.61±8.51 years in the intervention and control groups, respectively. Women comprised 73.7% (n=59) of the study population. The mean score for the self-care and self-efficacy questionnaires in the experimental group was 23.50±6.58 and 18.57±6.64, correspondingly, before the intervention, which increased to 42.64±6.74 (P<0.014) and 32.29±7.06 (P<0.001), respectively, shortly after the intervention. A significant improvement also occurred at 3 months' follow-up (P<0.001). Self-care behaviors also revealed a positive correlation with self-efficacy shortly after the intervention (r=0.82, P<0.001) and 3 months after the intervention (r=0.85, P<0.001). Conclusion: The implementation of educational interventions based on self-efficacy strategies could have positive effects on health-promoting behaviors among heart failure patients.

Rationale for targeted self-management strategies for breathlessness in heart failure

To provide a conceptual rationale for targeted self-management strategies for breathlessness in chronic heart failure. Breathlessness is a defining symptom of chronic heart failure and is the primary cause for hospital readmissions and emergency room visits, resulting in extensive health care utilization. Chronic breathlessness, punctuated by acute physiological decompensation, is a sentinel symptom of the heart failure syndrome and often intensifies towards the end of life. Drawing upon evidence-based guidelines, physiological mechanisms and existing conceptual models for the management of breathlessness is proposed. Key elements of this model include adherence to evidence-based approaches (pharmacological and non-pharmacological management to optimize heart failure treatment), self-monitoring of symptoms, identification of modifiable factors (such as fluid overload), and targeted strategies for breathlessness including distraction and gas flow. Self-management is an essential component in heart failure management which could positively influences health outcomes and quality of life. Refining programs to focus on breathlessness may have the potential to reduce symptom burden and improve quality of life.

Cross-Cultural Adaptation and Reliability of the French–Canadian Version of the European Heart Failure Self-Care Behaviour Scale-9

Background and Purpose

The purposes of this methodological study were to adapt the European Heart Failure Self-care Behaviour Scale-9 to the French–Canadian population and to evaluate its reliability.

Methods

The adaptation process consisted of translation, back-translation, evaluation by an expert committee, and pretesting. Reliability was evaluated with stability criteria (test–retest) and internal consistency.

Results

Pretesting led to testing of two response formats: 5-point Likert scale and the frequency scale. Both demonstrated good levels of agreement between the test–retest, although the values were higher with the frequency format. The Cronbach's alpha coefficients ranged from 0.71 to 0.78 (Likert scale) and 0.70 to 0.83 (frequency scale).

Conclusion

The French–Canadian version of the EHFScB-9, in both formats, demonstrated good evidence of reliability.

The Self-Care of Heart Failure Index: A psychometric study

BACKGROUND

The Self-Care of Heart Failure Index is an empirically tested instrument to measure self-care of heart failure patients across different populations and cultures.

AIMS

To develop and evaluate the psychometric properties of the Nepali Self-Care of Heart Failure Index.

DESIGN

This psychometric study used a cross-sectional, observational, study design to collect data. The study was guided and reported following the Strengthening the Reporting of Observational Studies in Epidemiology guideline.

METHODS

To develop and culturally validate Nepali Self-Care of Heart Failure Index, a combination of the recommended methods for cross-cultural validation studies were applied such as translation, back translation, expert committee review of the translated version and validity/reliability testing. Face and content validity were ensured using expert review. Construct validity was examined using exploratory factor analysis and confirmatory factor analysis. Composite reliability scores were calculated for each sub-scale of the Nepali Self-Care of Heart Failure Index.

RESULTS

A total of 221 heart failure patients in Nepal were enrolled in the study. Adequate face and content validity were ensured through expert review. Exploratory factor analysis and confirmatory factor analysis supported the original three-factor model. Although the three factors explained only 41% of the variance, confirmatory factor analysis fit indexes and error measures were found reasonable. The composite reliability coefficients for self-care maintenance, management and confidence scale were 0.6, 0.7 and 0.8, respectively.

CONCLUSIONS

The Nepali Self-Care of Heart Failure Index is a theoretically based, culturally acceptable and appropriate instrument for use among Nepali heart failure patients. However, further studies are needed to refine its psychometric properties.

RELEVANCE TO CLINICAL PRACTICE

Access to reliable, valid and culturally appropriate instruments is crucial in describing the state of the problem as well as for developing and evaluating tailored and targeted self-care practice interventions for Nepali patients living with heart failure.
